Application filed August 10, 1914. Serial No. 856,031.

To aZZ uflwmat may concern Be it known that I, DWARD Moonn, a citizen of the United States, and resident of Syracuse, 1n the county of Onondaga, in

the State of New York, have invented new and useful Improvements in Motor-Tractors, of which the following, taken in connection with the accompanying drawings, is a full,

clear, and exact description.

p This invention relates to certain improvements in motor tractors adapted to be used more particularly for farm work-for operating plows, drags, harrows and other tilling implements requiring repeated traversing of a field, or it may be temporarily installed in any convenient locality for operating other machinery, such" as threshing, wood-sawing, silo-fillingand fodder-cutting machines, as well as any other devices which might be operated by motor power.

The main object, therefore, is to provide a commercially practicable and economical motor truck or tractor which may be propelled under its own power and used for all the purposes mentioned, without in any way altering its structure.

Another object is to render the operation and control 'of the machine so easy and simple that janyone skilled in the handling of ordinary farm utensils may successfully operate the same.

A further object is to localize all of the controls within easy reaching distance of the operator at a particular part of the truck so that the machine may be steered, propelled forward or backward at any speed, or stopped, Without necessitating change of position of the operator.

A still further object is to distribute the driving members for the traction wheel in such manner as to equalize the driving strain thereon, so that it may run with a minimum amount of friction and thereby increase the durability of this important part of the machine.

Another-important object is to drive the traction wheel through the medium of a single concentric row of gear teeth, having internal and external Working faces, on the same pitched circle and in spaced relation so as'to permit the driving pinions cooperating withsaid working faces to expel any dirt, stones or other foreign matter which may tendto lodge or accumulate between the gear teeth.

Other objects and uses relating to specific parts of the machine will be brought out in the following description.

In the drawings, Figures 1 and 2 are respectively a top plan and aside elevation of a motor tractor embodying the various features of my invention. Fig. 3 isa horizontal sectional view of the same machine taken on line 3.3, Fig. 2, except that it omits the front end and left-hand side of I the machine carrying thesteering and land wheels. Fig. l is a, longitudinal vertical section through a portion of the left-hand side of the machine showing more particularly the mechanism for shifting the sliding disks, and taken on line l--l, Fig. 3'. Fig. 5 is an enlarged detail section taken on line 55, Fig.3. showing the universal bearing for one of the comiter-shafts. Fig. 6 is an enlarged detail sectional view taken on line 66, Fig. 3, showing the hinged bearing for one of the counter-shafts. Fig. 7 is a vertical sectional view through the front end of the machine. taken on line 7T, Fig. 1, showing the steering gear. Fig. 8 is a vertical sectional view through the left-hand side of the frame near the land wheel, showing the manner of adjusting said wheel vertically, and taken on line Sb. Fig. 1. Fig. 9 is a vertical sectional view through a portion of the rear end of the machine, taken on line 9-4), i. Fig. 10 is :1 detail sectional view through the center portion of the machine, taken on line 'l )--l(,) Fig. 1, showing more mrticularlv the equalizing lever for shifting [he l'rirtion lll li$ along their respective cmniu-r sliaits. Fig. ll.v i an -enlarged transverse vertical sectional view taken on line ll--ll, Fig. showing the hand lever and foot lever for controlling dimensions of the wheels -2- and 3 so,

as to constitute the main support for the frame -l and mechanisms carried there by, and at the same time to afford ample traction surface-for propelling the machine,

and other implements attached thereto, along or upon the surface of the ground.

The main frame 4 is elongated in the direction of the line of draft and comprises outer and inner lengthwise parallel bars 5 and 6 of substantially the same length and constituting one side of the frame, said bars being held in fixed spaced relation by relatively short end and intermediate cross bars 7-, -8 and -9- which are secured to the lengthwise bars -5 and 6- by junction plates 10,

.the rear cross bar -8 and intermediate bar -9 being spaced apart a suflicient distance to receive the traction wheel 1 bctween them, While the front bar 7 and intermediate bar -9 are spaced a relatively shorter distance apart to permit the free'operation of the steering wheel -2-- in the intervening space.

The rear bar -8- is provided with an extension 8- toward the opposite side of the machine, the outer end of said extension being rigidly united by a junction-platehaving its inner end rigidly united to the plate --10 and its outer end similarly united to the bar -1lby means of a j'unction-plate 15-.

As a. further means of stiffening the frame and supporting the enginedicd, presently described, the junctions of theextension 8' and bar 12 at the rear of the machine are connected by a lengthwise bar 1(3 to the bar 1ljust at the 'rear of the cross bar 9-, said bar 16 being spaced some distance from and parallel with the bar 6 and has its rear end rigidly secured to the j unction-plate' -11 and its forward end secured by a similar junctionplate l1- to the bar '""1?t', all of said frame bars'being preferably made of channel iron for lightness and strength.

The frame bars 12 and -1+- are disposed diagonally to the line of draft, so as to converge in approximately the vertical plane of the produced axis of. the traction wheel 1-, in which plane the axis of the land wheel ,3 is located, said diagonal bars -12- and -ll-, together with the extension cros bars -S and 9 and lengthwise bar -16,

may be termed an outrigging for supportconstituting what ing the land wheel 3- and other adjuncts of the machine hereinafter described.

The traction wheel -1 is journaled upon a relatively short stationary cross shaft 17 having its ends secured in suit: able boxes '18 on the lengthwise frame bars 5 and'(3- by means of set screws thereby supporting the traction wheel in the open space between the length-. wise bars i-"and -6-, and also between the cross bars S and '9-. This traction wheel comprises a hub 20- having flanged ends connected by circular plates or webs -21 and -22 to a circular flanged rim having a traction tire 2l riveted or otherwise secured thereto, the inner and outer marginal edges of the circular plates or wel)s21' and 22 being also riveted or otherwise secured to the flanges of the hub -20 and rim 23-,' thereby forming a light, yet strong and durable, traction wheelflcapableof excluding the dust from the interior thereof. i

The inner disk -22 is provided with a concentric. row of axially projecting gear pins or teeth 25 of circular cross section so as to form internal and external working faces having a common pitch circle, and

adapted to meslr respectively with an internal pinion -2G- and an external pinion Q6-. These pinions are secured to the inner ends of separate counter-shafts -27 and -27- which are journaled in bearings -28- and i 9 parallel with-and at opposite sides of the axis of the traction wheel, as shown more clearly in Fig. 3, for receiving and supporting separate friction disks 3()-. Thesefriction disks are feathered or splined upon their respective countershafts -QT and -2T' to "rotate therer withand to nuivc-axially thereof. and for this purpose the counter-shafts are angular or square in cross section and are passed through corresponding openings in the centers of the disks -30'.

Rotary motion is imparted to thedisks 30 'by means of cooperative driving disks -31 which are secured to the opposite ends of a motor shaft 32-. the latter being j ournaled on a bed-plate 33 bridging the space between the lengthwise bars and 1(3-- and bolted or otherwise secured thereto, The motor shaft 32 is disposed at right angles to and in approximately the same plane as the axis of the traction wheel, so that the disks --3l are disposed at opposite sides of said axis for frictional contact with the inner faces of the friction wheels 30-.

The outer end faces of the disks -31-. 5

tion or the other,

the sliding disks their corresponding shafts '27- and 7''and pinions 26 and 26'- in reverse directions,.thereby imparting rotary motion to the traction wheel in one direcaccording to the position ofthe driven disks 3( at one sideor the other of the axis of the motor-shaft, it being understood that the disks 30- may be movedto either side of said axis for reversing the direction or changing the speed of movement of the machine, or they may be stopped at the center, when the machine will, be at rest. Y

Suitablei means providedofor moving ,30 axially and simultaneously the same distance in the sa ine. direction, and for this purpose the hubs of the disks 30- are provided with annular "grooves for receiving non-rotatable collars aving pins projecting into the grooves, said collars being pivotally con nected to crank arms which in turn are-secured to vertical rock shafts 36- and 3fi on the rear bar -8 and in- These rock shafts are provided with crank arms-37 and 37 extending in the same direction towirid'the traction Wheel from their respec-' .tive shafts -36 and ,36- and have their free ends connected by links 38' a and 38 to the opposite ends. of an equaldisks '50 izi'ngylever. .39, which -is fulcrumed or pivoted intermediate its ends at -t(lto theunder side of the bed-piate -33 as shown more clearly in Fig, 10, the rock shaft 36 being also provided with an oppositely pro ecting crank arm 41 having ts free end connected by a link to the lower end of a hand lever which is fulcrumed at,44 tothe lengthwise frame bar -16 as shown in Figs'.4and11.',

It is now clear that by rocking the lever '-43. forward and backward simultaneous axial movement will. be transmitted to the 30 to move the same across the face of the disks 31 toward) and from t he center and to either side thereof for varying the speed and reversing the direction of movement of the traction wheel, medium of the counter-shafts 'Z- and -27' and pinions -26- and 29+, For example, assuming that'the friction disks -30, are in the position shown in, Fig. '3, atone side of-the axis of the motor shaft for driving the machine in one direction, I verse. the -.machine,'then it is simply necessary to rock the upper-end of the: lever 43 forwardly a sufficient distance to slide the disks 30' to the opposite-side of the motor shaft, under which conditions and that His desired tore-* shafts are rocked away from each other ln/ the link 42, will be moved in the direc- 38-- will be moved in the opposite direetion indicated by arrow Y, thereby operating the lever 39 to shiftthe link -38 in the direction indicated by arrow Z, the several crank arms, lever and links being so relatively, arranged and proportioned as to transmit the same amount of movement to the disks -30 in the same direction by a predetermined degree of movement of the operating lever -l3.

One of the objects in applying the driving pinions -26 and 26'- internally and externally to the corresponding working faces of the gear pinions -25 at diametrically opposite sides of the axis of thetraction wheel, is to substantially balance the driving strains and to relieve the traction wheel from binding upon its shaft '17, thus producing a maximum propelling power without loss or excessive wear.

Another object is to render the intermeshing gears self-cleansing from dirt, stones andother foreign matter which may tend to lodge between the gear pins, since it is evident that anymatter which may wedge between the teeth from one side will be forced out by the teeth of the pinion acting from the opposite side.

In order to increase the utility of this purposes than propelling 2, which permits the use of the motor shaft for driving a general utility shaftl6- which is journaled in suitable bearings 47 directly over and upon the lengthwise bar 16- of the main supporting frame, said utility shaft beingprovided with a sprocket wheel-connected by a chain -48? to a similar sprocket wheel -48 on the motor shaft -3Q., as shown more clearly in Figs. 1, 2 and 3. a t

The bearings -28- for the inner ends of the counter-shafts 27- 'and 27 are .mounted on horizontally swinging arms 49 which are pivoted at 50 to brackets .51 on the inner main frame bar as shown more clearly in Fig. 3, the

pivots 50 being in radial alinement with and close to their corres g Pinions 2( and -26 so as to prevent disengagement of the pinions with the gear teeth- -25,' whenthe outer ends of thekc'ounterdisengaging their disks -30- from their driving disks '31 I the counter-shafts -27- and 7- are bar 16, and is adapted to be forced upmounted upon the upper ends of upright rock arms which are 1ournaled in suitable bearings 5-l on the lower side of the frame bar 1(3-, and are provided with crank arms '-55 extending from their bearings -5i toward eachother, the adjacent ends of said arms 55- being pivotally connected to links -56 which in turn are pivoted to the opposite ends of a lever =57-. This lever is fulcrumed intermediate its ends at 58- upon the lower end of a vertically movable rod or plunger 59- which is slidable in a bearing (S0 on the frame wardly by a pedal lever (31 against the action of a retracting spring 62, the latter being interposed between the lower end of the bolt -59 and adjustable bushing --("i in the bearing (50.

The pedal lever 61- is made in the form of a bell-crank fulcrumed at 61'- to a bracket on the under side of the frame bar -16-- and having its shorter arm engaged with the lower face of the lever 57-and its longer arm extended upwardly above the frame bar 1(i, and provided with a foot piece 64.

The spring '2 normally forces the disks 30- into engagement with the driving disks 31 through themedium of the arms 55 and 53, but by pressing forwardly upon the upper end of the foot lever -l' 1 the shorter arm thereof, operating upon the lever 5T rocks the arms 5?- upwardly. thereby rocking the arms 53- and adjacent ends of the counter-shafts 27 and 27 carried thereby away.

from each other to disengage the corresponding disks -30 from said driving disks, the

bearings -29- being swiveled in the upper ends of the arms to allow the lateral rocking movement of the counter shafts -2T- and -2T about the pivots 50- of the supporting arms 49- for the inner ends of the rock shafts, in the manner previously described. The object of these special mountings for the counter-shafts is to permit them to be moved laterally to disconnect their disks -30- from the driving disks -3l without cramping-said shafts or disconnectil'ig their pinions from the gear teeth The steering wheel 2 is ournaled in a suitable fork -T0- having its upperend provided with a spindle 71 which is journaled in a plate 7Q- connecting the front ends of the bars 5 and -6 and securedthereto by suitable bolts, as shown more clearly in Figs. 1 and 7, the port-ionof the fork 7U-+ at. the junction with the spindle 71 being provided with a relatively broad flat bearing in turning engagement with the underside of the plate 72.

- steering wheel.

In order that the steering wheel may be operated positively in either direction, the flexible shaft 75- is preferably composed of end and intermediate sections, as shown more clearly in Fig. 1, the intermediate section being journaled in the bearings 76- and its opposite ends connected by universal joints --7.8 to the end sections.

The land: wheel -3 is ad'ustable vertically and for this purpose is mounted on an axle stub 79, preferably square in cross section and slidable vertically in a U-shape. yoke -80- which is secured to the under side of the bar -1i-, said axle stub being provided with a\ transverse bolt opening I adapted to register with any one of a series of similar openings -92-' in opposite sides of the yoke for receiving av locking pin 93- by which "the axlestub and land be held in any of its ad- Any suitable motor, such as an inte a1 combustion engine, may be mounted u on the bed-plate 33 and connected to the" crank shaft 32 in the usual manner.

The auxiliary shaft l6 may be provided at its rear end with a clutch section" 95 for engagement by a starting crank 96 to start the engine, although it is evident that any -of the well known forms of self-starting devices may be employed if desired, and that the clutch may be used for connection with any other shaft or machine which it is desired to drive, either simultaneously with the operation of the traction wheel in propelling the machine along the ground or independently of the propulsion of said machine.

i A suitable seatfor the driver, not shown, may be mounted upon the main supporting frame within convenient reaching distance of the steering wheel -'77- and levers 43 and -'61 by which the operation of the machine; is controlled. T

It is alsor evident that a plow barrow, cultivator or; any other implement which it is desired to operate by means of the tractor may be attached thereto by any suitable means, not necessary to herein illustrate or describe for the reason that the attaching. means will depend somewhat upon the implement propelled by the tractor.

In operation. the speed and direction of movement of the machine is controlled entirely by the lever -43-, while the driving connection between the friction trolled by the pedal lever 61, the auxiliary shaft 46 being driven at all times when the motor is in operation.
